Hi,
I have am working on a project to automate a mine site. There are a number of PLCs with EN2Ts, EN2TRs and ENBTs. I am trying to write an AOI to check the status of any one of these Ethernet cards and report if they have an IP address assigned, are healthy, are connected to the network, etc...
I am not looking to check that comms are healthy to all my remote devices. I am doing that with separate logic.
My plan is to generate a health/fault bits to indicate that the Ethernet module is healthy and running and use it to mask alarms for comms faults to remote devices.
I know there are multiple options to check the status of the modules – GSV instructions and CIP MSG instructions. Could anybody suggest the best method or most common practice method for detecting Ethernet module health status?
Cheers,
Nick
